“The only action that will keep the Postal Service from insolvency and a potential disruption in service is for Congress to pass comprehensive postal reform legislation, but that can’t happen until the House passes a bill,” Carper said in a statement. “The longer the House delays action, the more losses the Postal Service racks up.”

Ali Ahmad, a spokesman for Rep. Darrell Issa (R-Calif.), who chairs the House Committee on Oversight and Government Reform, did not address the timetable for House action, but said the Senate bill “would ensure that USPS’s staggering losses continue in both the short and long term, and risk the Postal Service becoming a permanent burden to the American taxpayer, according to USPS leaders.”
